Blade

you should just mash D as hard as you can because there's no chance of getting accidental charge lasers. as long as you are pointing the right direction at the right time it's pretty easy to keep up. also the 2D 4D xN works if you are at exactly starting length or a bit closer. if you're too far they get pushed out, and too close they get knocked into the air (can probably combo, but it would be less damage and harder than spamming)
